Life hadn't been kind to me lately. My girlfriend, Becky, had just broken up with me and the university I was supposed to be going to had rescinded my acceptance because of low application numbers for the course I was doing. My sister, Rosie, was newly single at the time too. She had been going through a rough time since her own recent break-up. She had moved home, out of her shared apartment and she spent a lot of time in her bedroom now, with the door closed and loud music playing. I assumed that she spent that time crying. I had gotten out of bed to go to the toilet when I noticed her door was slightly ajar. I peered inside, making sure she was okay and what I saw was breathtakingly amazing.
She lay on her bed in front of her large vanity mirror; fully naked and softly moaning as she played with her shaved pussy. I stood back and watched for a few minutes as the gorgeous blonde with ocean blue eyes finger fucked herself, while teasing her perky B cup breasts. Just watching and listening, I could feel my shaft getting harder and harder, until it was rock hard and pushing at the briefs I was wearing.
Eventually my stiff cock led me into her bedroom. Rosie barely noticed me as she continued to rub herself, her moaning continuing. When she did finally notice me, she looked shocked and worried at my presence before relaxing and smiling brightly at me. Then she glanced at my rock-hard cock trying to escape my underwear.
"How long have you been standing there?" She asked, slightly out of breath as her pussy teasing slowed.
"A... A few minutes." I stammered out, her body fully exposed in front of me.
"Want to help me out?" She asked, smiling even brighter.
"Uhh, sure... What do you need?" I was so nervous that night, I kept stumbling on my words.
"Just take off your clothes and kneel down just here." She patted a spot on the floor between the mirror and her bed and then watched as I stripped for her.
I took my shirt off, showing off my slowly developing 6-pack before pulling down my briefs and exposing my 7-inch shaft to her. I got on my knees in the spot she specified and much to my surprise; she moved herself in front of me and spread her legs wide, exposing her gorgeous vulva.
"Are you ready to help me, hunny?" She smiled warmly, comforting me. I had barely nodded my agreement when I felt her hands moving through my hair to a position at the back of my head.
Rosie pulled my head in nice and slowly, towards her glistening vulva. It was already dripping wet, when my lips first met it. I felt her body shudder as my lips glanced off of her clit.
"Do your thing baby, do your thing." Was all she managed to get out through her shaky breaths. With her hands still firmly on my head, pushing it onto her vagina, I began to gently lick her lips, feeling her body shudder and moan every time my tongue flicked over her clit.
